Forging of Positive and Negative Teeth Single Plate Aluminum Alloy for Highway Vehicles

anodic oxidation

36T-58T optional

Positive and negative teeth with narrow width and tooth shape design are not easy to drop chains. Standard 5 disc hole BCD110MM installation specifications have high compatibility and are suitable for various 5-jaw mountain cranks

Aluminum alloy forging anodizing

High precision positive and negative tooth positioning

Arc cutting angle, strong engagement force between positive and negative teeth positioning slots, reducing vehicle load, ensuring smooth and powerful operation without chain breakage during cycling

All aluminum alloy forging surface with strong anodizing, impact resistance, and obvious rust prevention effect

The inclined mouth of the mud discharge prevents sediment accumulation, and the teeth run smoothly

Strong biting force of positive and negative teeth positioning slots

Arc cutting angle, positive and negative width, narrow tooth shape design, reducing chain wear, strong biting force, and high efficiency transmission

Anodic oxidation of aluminum alloy forging surface

All aluminum alloy has strong forging strength, strong impact resistance, uniform stress, smooth cycling, and surface anodizing, effectively protecting the aluminum alloy body and preventing surface rust and oxidation

All CNC integrated molding

Lightweight aluminum alloy fully CNC process, with strong rigidity and high hardness; Stable structure without deformation due to intense stepping, greatly improving durability

Multiple muscles share uniform output

Balanced stepping output helps to better maintain physical fitness; Provide 36T-58T teeth selection for use with 110BCD highway vehicles with 5-jaw cranks.
